Beit known that I, WILLIAM H.'Pn 'i 'mcrr,

.fiecitlzen'of the United :States residing at .-Spokane, in the 'county of 'of the character shown andv described in the a pication of Goodman and Holden, 1Se' ria l Number 138,771, liled December .26 1916; and has forits object to simplifyand im'prove the construction and operation of a' truck of this character.

The present structurel includes novel j means of connect-ing. the roller bearings to the turnable ring infposition to support the stationary ring, the rollen bearings being in whichjournaled in -carryn frames, which latter are connected dlrect y tol and su ported' e upupon the turnable truck ring. wardly bowed straps or truss.bars, carried onthev axle of the truck, have their adjucent ends connectedtogether by arcuate plates; upon which the ring of the truck frame is supported, said'ar'cuate plates'alsof -being extended beneath the ring onV the ve-v hicle frame to assist 'in supporting the same and to llmit. the rocking movement between .the two rings. Otherwise'there isfa general ,simplification or rearrangement of the parts throughout', .whereby toproduce a more economical construction and onecapable of easy assembl1ng.' A preferredforni of my mvention 41s exemplified in the following .description and illustrated in 'the accompanylng drawings',

Various changes in the construction and l arrangement of the several parts herein shown and described maybe employed without departlng from the spirit of my invention as disclosed in the appended claims.

"' Having' thus described ,lny invention,

what I ci'iiini and desire to secure by Letters.

latent is- 1. A steering truck for vehicles comprisinfga wheeled axle, relatively tu'rnable inner and outer cylindrical rings, one carried h v the vehicle frame and the` other by the truck. the latter serving as a sole guide for the vehicle ringand the interior of the rings being open and unobstructed to permit the upper portion of the truck wheel to project within, and roller bearings depending from the truck ring and lying eueath the vehicle 'ring to support the latter.

v 2 rtrsteering truck for vehicles comprising a wheeled axle, relatively turnable inner and outer cylindrical rings, one carried by, the vehicle frame and the other by the truck, the latter serving a sole guide for the vehicle ring.r and the interior of the rings y being open andunobstructed to permit the upper portion4 of the truck wheel to project '.w'thin, roller bearings depending from the truck ring and lying beneath the vehicle ring to support the latter, and means for supporting the truck ring upon the axle of the truck comprising fore and vaft extending, upwardly bowed truss bars and upwardly extending supports near each end ofthe axle inline therewith and secured to the adjacent sides of the truck ring.

3. In a steeriiig truck for vehicles, rela- -vtively turnable inner and outer cylindrical rings. the outer one carried by the vehicle frame and the inner one by the truck, roller carriers detachably connected to the inner circumference of the truck ringat diametri'cally opposite points and extending downwardly and beneath thev outer ring, and al plurality of" roller bearings -journaledin each carrier and engaging beneath and supporting the vehicle `rlng. l

l. A steering truck comprising a wheeled axle. upwardly bowed truss bars thereon eixtending transversely of the axle, tie bars conncctin the upper ends of .each trussbar,

arcuate p ates connecting 'the adjacent ends of opposite truss bars, a ring fixedupon the arcuate bars, roller bearings carried-'by said 'ril-1g, and a rin carried by the vehicle ysection and each. having a vertical yflange lying outside ofth'e vehicle ring.

6. A steering truck for vehicles l'compris-y ing a wheeled 'ax-le. upwardly bowed truss 80 bar-- thereon extending transversely' of the axle,l tie bars connecting the upper ends 0i each truss bar, arcuate plates connecting adjacent ends of'opposite truss bars., a ring lixed upon the arcuate plates, brace bars connected to the rin at points opposite to the sides of the truce wheel and extending dowmvardly and connected to the axle, a roller carrier detachably connected to the ring intermediate-the points of connection '90 of the truss and brace bars therewith, a ring carried by the vehicle frame telescopically fitted A over the first mentioned ring, and roller bearings journaled in .said carriers-in posit-ion to engage beneath the vehicle ring and support the same.

7 A steering truck for vehiclescomprisaxle,.tie`bars connecting the upper ends of 10.

' each truss bar, arcuate plates connecting adjacent ends of opposite truss bars, a ring fixed upon the arcuate plates, brace barsconnected to the ring at points opposite to the sides of the truck wheel and extending ,10. dow-. nwardly and connected to the axle, a roller carrier detachably connected to the ring intermediate the points of connection of the truss and brace bars therewith, a ringcarried by the .vehicleframe telescopically fitted over the first mentioned ring, roller bearings journaled in said carriers in position to engage beneath the vehicle ring and support the same, and fastening bars extending parallel with the tie bars,l overly- 11n ingbothrings and connected to said tie bars.
